Hi, I have what is probably a dumb question so it should be an easy one for gurus.
I built two VM's on VirtualBox using my Orabuntu-LXC software. The VM VNIC's are ports on OvS sw1 on each VM. The VM's are on the same physical host. I have LXC containers on the sw1 switch also. What has surprised me with this setup is that I can ssh between containers that are on different VMs and all the network devices, the VNIC's and the OvS switches, and the physical interface on the host, are all set to MTU 1500. Not anywhere in this setup is MTU 1420 used. My understanding was, and what I have found in all previous cases, was that I had to use MTU 1420 for ssh over a GRE tunnel to allow for encapsulation, so my question is I am wondering how can ssh be working over this GRE tunnel when all the MTU of all devices is set to 1500?
